Using The Performance Table
Shown below is a portion of a typical performance table used in this catalog. Performance data shown
offers the best selections for each propeller type (“L” or “H”) relative to sound, RPM and static pressure.
Consider “L” type propellers first for most applications.
Many sidewall applications can be met with the “L” type propeller. When using the performance tables, look
first at the “L” selections, because they offer the lowest speed and sound levels.
20 Belt Drive SBE/SBS
Model SBE for exhaust — Model SBS for supply
Performance certified is for Models SBE/SBS for installation type A: free inlet, free outlet. Power rating (BHP) does not include transmission losses.
Performance ratings do not include the effects of appurtenances (accessories).
* Speed (RPM) shown is nominal. Performance is based on actual speed of test.
The sound ratings shown are loudness values in fan sones at 5 ft (1.5 m) in a hemispherical free field calculated per AMCA Standard 301. Values are for installation
type A: free inlet hemispherical sone levels.
*Sones shown apply to the highest cataloged CFM in black type at each fan RPM. For selections at other CFM and static pressure points, refer to the CAPS
computerized selection program.
